Module Aims
|
The objective of this course is that, on completion, each student should have acquired a basic competence in the special problems of software development for embedded systems.
This will include proficiency in one microprocessor assembler language (Motorola M6809) and the integration of a microprocessor assembly language (Motorola M6809) with a high level language (C). This will be supported on a general-purpose cross-development platform (Intel x86 PC compatible hardware, running MS-DOS).

Learning Outcomes
|
Having successfully completed this course, the student will:
1. Have acquired a basic competence in the special problems of software development for embedded systems.
2. Have a proficiency in one microprocessor assembler language (Motorola M6809).
3. Have the ability to design and implement hybrid 'C' / assembly language programs

Indicative Syllabus
|
|
· Introduction: Role and operation of the CPU. The microprocessor as a CPU in integratedcircuit form. Concept of an embedded system. Development system software.
· Basic CPU concepts: CPU architecture. CPU registers and the M6809 register model. General purpose, pointer (including program counter), and flags registers. The concept of instruction set. Assembler features. Assembler directives. One/two pass assemblers. Examples based on M6809, including discussion of native-versus cross-assembly. Linker concepts. Macros.
· Introduction to assembly language: Machine language programming. Intelligibility problems.Use of instruction mnemonics. Use of mnemonic labels in control flow. Automatic translation of mnemonics the assembler. Outline instruction set. Operands.
· Addressing modes: Inherent, register, immediate, base page direct, extended direct, indirect, extended indirect and indexed. Addressing mode examples based on M6809. Program relative addressing for branches.
· Stack concepts: Concept of a stack. The push and pop operations. Stack overflow and underflow. Use of stack to provide basic procedure linkage. Use of stack to provide temporary storage. Examples based on M6809.
· Problems: Simple register manipulation. Look up tables. Program loops. Character-coded data. Code conversion. Arithmetic problems. Writing position-independent code. Subroutines. Parameter passing techniques.
· I/O concepts: Integrating I/O. Problems of synchronisation with external events: polling (continuous and intermittent) and use of interrupts. Examples based on M6809 family I/O interface devices. Memory maps. Practical problems associated with using interrupts. Interrupted related instructions.
· Compiler concepts: Problems with assembly language programming: lack of portability (of applications and/or expertise); impoverished data and code structuring facilities. Solutions provided by high level language. Problems with use of high level language: access to special purpose instructions; size and speed efficiency. Solution based on combining assembly and high level language programming. Examples based on M6809 and C language.
